Complex DC-offset cancellation circuit
Electronics Letters, 2009 A novel DC-offset cancellation circuit that is applicable to complex filters is presented. The proposed circuit allows for a high-gain complex filter, which leads to a small chip size and low current consumption. Adopting the proposed scheme, a 10 to 73 dB gain complex filter that cancels an input referred DC-offset by more than plusmn100 mV is ...

DC Offset Error Compensation Algorithm for PR Current Control of a Single-Phase Grid-Tied Inverter
Energies, 2018 In a single-phase grid-tied inverter, the direct current (DC) offset error included in the measured grid side phase current has various causes, such as a non-ideal current sensor, unbalanced power supply of an operational amplifier, and nonlinear ...

Application of the DC Offset Cancellation Method and S Transform to Gearbox Fault Diagnosis
Applied Sciences, 2017 In this paper, the direct current (DC) offset cancellation and S transform-based diagnosis method is verified using three case studies. For DC offset cancellation, correlated kurtosis (CK) is used instead of the cross-correlation coefficient in order to ...

Programmable Gain Amplifiers with DC Suppression and Low Output Offset for Bioelectric Sensors [PDF]
Sensors, 2013 DC-offset and DC-suppression are key parameters in bioelectric amplifiers. However, specific DC analyses are not often explained. Several factors influence the DC-budget: the programmable gain, the programmable cut-off frequencies for high pass filtering

Noncoherent block detection in the presence of DC offset [PDF]
IEEE Transactions on Wireless Communications, 2006 In this paper, we deal with noncoherent detection of a digitally phasor block-modulated signal in the additive white Gaussian noise channel when a direct-current (DC) offset is present in the receiver baseband processing. By processing the received baseband signal block by block, a generalized linear transform is used to remove the offset prior to data

Simplified sympes codec with positive DC offset
2017 24th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2017 In this paper, further improvement is reported in the simplified version of the Sympes voice encoding algorithm. A drastic reduction in the computation time of the algorithm is achieved by introducing an offset in the amplitude of the normalized speech signals which enables trusted, secure and real time voice communication over computer networks and ...
